Android自定义样式

1、AndroidManifest.xml

android:theme="@style/Theme.CustomDialog

样式要用：@style

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.fish.helloworld"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="17"
        android:targetSdkVersion="17" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/Theme.CustomDialog" >
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_receive" >
             <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

2、styles.xml

<resources>

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
    <style name="AppBaseTheme" parent="android:Theme.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    </style>
    
    <style name="Theme.CustomDialog" parent="android:style/Theme.Dialog">
        <item name="android:windowBackground">@drawable/filled_box</item>
    </style>

</resources>

3、filled_box.xml

一定放在drawable文件夹下，否在不识别

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#ffff8080" />
    <stroke android:width="3dp" color="#ffff8080" />
    <corners android:radius="3dp" />
    <padding android:left="10dp" android:top="10dp"
        android:right="10dp" android:bottom="10dp" />
</shape>
